Answer:
A: a = 100
B: b = 2
Step-by-step explanation:
The problem statement tells you that the population of bacteria is 100 at the start of our observation.
t = 0, f(t) = f(0) = 100
If you remember that a 0 exponent means the value is 1, then you know ...
f(0) = a·b^0 = a·1 = a
Since f(0) = 100, we know a = 100.
__
An exponent signifies repeated multiplication.
We know the population at t=0 is 100. At t = 1, we are told the population doubles. That means it is multiplied by 2.
f(1) = 100·b^1 = 100·2
b^1 = 2 . . . . . . . . . . . . . . . matching parts of these expressions
b = 2 . . . . . . . . . . . . . because b^1 = b

Ross bought a TV for $1,200. She sold it with 25% loss. How much did she lose?
Answers
Step-by-step explanation:
loss % = 25%
loss = $1200 × 25 ÷100
= $30000 ÷100
= $300
selling price = cost price + loss
= $1200 + $300
= $1500

In △ABC, G is the centroid and BE = 21. Find BG and GE.
Answers
Answer:
BG = 7, GE = 14Step-by-step explanation:
The centroid is the intercession of medians.
The centroid theorem states that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.
BE is the median and point G is 2/3 of the distance from E:
GE = 2/3BE = 2/3(21) = 14Then BG is:
BG = BE - GE = 21 - 14 = 7The answer is BG = 7, GE = 14
Answer:
the answer is BG=7,GE=14
Leah is financing $340,000 to purchase a house. How much money will she save over the life of a 30-year, fixed-rate loan by buying 3 points with a rate of 6.475% instead of not buying points with a rate of 6.85%?
Answers
Answer:
$38250
Step-by-step explanation:
Given data
P= $340,000
t= 30-year,
r1= 6.475%
r2= 6.85%
For r1
A= P(1+rt)
A= 340,000(1+0.06475*30)
A= 340,000(1+1.9425)
A= 340,000*2.9425
A= $1000450
For r2
A= P(1+rt)
A= 340,000(1+0.0685*30)
A= 340,000(1+2.055)
A= 340,000*3.055
A= $1038700
The difference is '

What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ΔABC
Let the second triangle be represented as ΔEAD
Now , the measure of side AC = 4.8
The measure of side BA = 3.1
And , the measure of side EA = 4.8
The measure of side DA = 3.1
And , Corresponding sides of similar triangles are in the same ratio
So , the triangles ΔABC and ΔEAD are similar
Therefore , the angles will also be congruent
The measure of ∠ACB = The measure of ∠DEA = x°
The measure of ∠DEA = 180° - ( 53° + 86° ) ( angles of a triangle = 180° )
On simplifying the equation , we get
The measure of ∠DEA = 41°
Hence , the measure of x = 41° and they are similar triangles
